Noga HSSE-Cobalt Countersink Set - 5 Piece, TiAlN

The Noga HSSE-Cobalt Countersink Set - 5 Piece is a Noga countersink tool for producing precise chamfers on drilled holes in metal. Noga countersink sets provide everything needed to chamfer and deburr holes in one kit, covering a range of diameters and materials. HSSE-cobalt construction gives extended life in stainless steel, titanium and other demanding alloys. Noga countersinking tools are used in production machining, aircraft maintenance and general fabrication where consistent chamfer quality is required.

Where this tool is used

• Machining shops where drilled and punched holes in steel, stainless and aluminium plate require chamfering prior to fastener installation or coating
• Aerospace and defence maintenance where fastener holes in airframe panels and structural components must meet chamfer angle and quality specifications
• Sheet metal fabrication where edge quality and consistent chamfer depth are required across high volumes

Key specifications

Selecting the right option

The NG3100 is Noga's standard countersink deburring tool for hand-held use. The EX3001 cranked RotoDrive countersink handles recessed holes and features where a straight tool can't reach. The HSSE-Cobalt and Solid Carbide sets are the right investment for stainless steel or hardened alloy work where standard HSS wears too quickly. The CS7000 power tool set suits high-volume chamfering with a power drill or die grinder. AIMS can advise on the right countersink for your hole sizes and production volume.
